The 2015 Pebble Beach Concours d’Elegance hosted many car debuts, including the 2017 Mercedes-Benz C-Class Coupe and a couple of BMW concepts, one of which is the 2016 BMW M4 GTS. Showcased more than a year after the new 2015 BMW M4 arrived, the Concept M4 GTS previews the much-rumored M4 GTS, a high-performance, track-focused coupe built in the vein of the limited-edition, 2010 M3 GTS and its iconic forerunners, including the 1988 M3 Evolution and the 2001 to 2003 M3 CSL.

"While the BMW M4 Coupe embodies the ideal combination of motorsport genes and unrestricted everyday usability, the BMW Concept M4 GTS previews an emotionally powerful and exclusive special model conceived with an eye for trailblazing technology and a keen focus on the race track," explains Frank van Meel, president of BMW M Division. "Despite its outstanding track ability, it is still fully road-legal. This is racing technology for the road in the truest sense."

The carmaker didn’t say how long until the production version arrives, but I wouldn’t be surprised to see it break cover by the end of 2015. Until then, let’s have a closer look at what appears to be a production-ready coupe.

Although the Concept M4 GTS is recognizable as an M4, there are a lot of add-ons setting it apart from its standard sibling. Up front, there’s an adjustable carbon-fiber splitter and a wider air intake. Both optimize air flow and minimize front axle lift, which is crucial for a vehicle that aims to take the M4’s performance to a whole new level. In addition to the carbon-fiber splitter that shaves a few pounds off the standard car, the GTS also received CFRP hood, which is lighter than a standard one so helps to lower the car’s center of gravity.

Further upgrades are visible around back in the form of a massive, adjustable wing and a slightly modified diffuser, both also made of carbon fiber. Rounding off the concept’s appearance are the "M4 GTS" badge on the trunklid and the OLED taillights. As a brief reminder, OLED, or organic light-emitting diode, is a new technology that produces full-surface and homogenous illumination, in contrast to LEDs, which emit light from a single point.

Aerodynamic enhancements aside, the M4 GTS is also wrapped in a special livery combining a Frozen Dark Grey Metallic paint with Acid Orange accents on the front splitter and the lightweight, forged polished wheels. Measuring 19 inches at front and 20 inches at the rear, the rollers are wrapped in Michelin Sport Cup 2 tires.

Expect all these features to find their way onto the the production M4 GTS, except for the orange accents, which are likely to remain exclusive to the concept car.

BMW had nothing to say about the concept’s interior, but it’s safe to assume it is largely based on the standard M4’s. Updates for both the concept and production cars should include a race-inspired steering wheel and pedals, and racing seats with multi-point harnesses, as well as a bespoke instrument cluster, a full rollcage and maybe a set of lightweight door panels.

Drivetrain

Powering the Concept M4 GTS is the same twin-turbo, 3.0-liter, inline-six found in the standard M4, but equipped with the same innovative water injection system used on the 2015 BMW M4 MotoGP Safety Car. Specifically, the new system injects water directly into the plenums of the intake manifold, where it is vaporized, resulting in a lower compression temperature in the combustion chamber.

BMW claims this translates into more horsepower and torque, but it doesn’t provide actual figures. If I were to take a guess, I’d say the six-cylinder unit generates around 450 horses, which is 25 horsepower more than the regular M4. The extra horsepower should shave a tenth-second off the M4’s 0-to-60 sprint, which takes 4.1 seconds with the manual and 3.9 seconds with the automatic transmission. I expect the same water injection system to be offered in the production M4 GTS as well.

With rumors of a new GTS-badged Bimmer flying around since 2014, this concept car basically confirms that Munich is indeed working on a second-generation GTS. Though not many official details are available right now, if the production car mirrors the concept’s aero upgrades and updated engine, we’re in for one cool track toy in 2016.

Press Release

A year on from the launch of the BMW M4 Coupe, BMW M Division is presenting an initial preview of a high-performance model for use on the road and, above all, on the race track: the BMW Concept M4 GTS.

The move sees BMW M Division once again returning to its roots. The BMW offshoot, founded in 1972 as BMW Motorsport GmbH, not only caused a sensation with its iconic BMW M1 racing car, but developed the first turbocharged engine to win the Formula One World Championship and was the force behind what remains the world’s most successful racing touring car – the Group A BMW M3.

And so the new BMW Concept M4 GTS continues the tradition of BMW M3 special models already illuminated by the BMW M3 Evolution (1988), BMW M3 Sport Evolution (1990), BMW M3 GT (1995), BMW M3 CSL (2003), BMW M3 GTS (2010) and BMW M3 CRT (2011). Technology honed in race competition, a hike in power, a commitment to lightweight design and limited production numbers have ensured these sharpest examples of their type offer unbeatable performance coupled with an emotionally powerful and exclusive driving experience.

“While the BMW M4 Coupe embodies the ideal combination of motor sport genes and unrestricted everyday usability, the BMW Concept M4 GTS previews an emotionally powerful and exclusive special model conceived with an eye for trailblazing technology and a keen focus on the race track,” explains Frank van Meel, President BMW M Division. “Despite its outstanding track ability, it is still fully road-legal. This is racing technology for the road in the truest sense.”

The BMW Concept M4 GTS showcases new technologies destined to make their series production debut in a new model to be unveiled at a later date. For example, the BMW Concept M4 GTS features the innovative water injection system that has already provided a significant output and torque boost in the BMW M4 MotoGP Safety Car. In addition, the BMW Concept M4 GTS has rear lights with OLED (organic light-emitting diode) technology that give the high-performance model a whole new look when darkness falls.

The world premiere of the BMW Concept M4 GTS takes place on 13 August 2015 surrounded by top-flight classic automobiles on display at the Monterey Car Week in California, USA.

Optimised down to the finest detail.
The BMW Concept M4 GTS builds on the BMW M4 Coupe’s dynamic and emotional use of forms. Yet its character as a high-performance special model, in which every detail has been developed to fulfil its purpose as a successful track machine, also comes immediately to the fore. The manually adjustable front splitter and rear wing – both in exposed carbon – ensure perfect aerodynamic balance and allow the BMW Concept M4 GTS to be adapted for both individual race tracks and for use on the road. Another example of the engineers’ rigorous adherence to lightweight design is the CFRP (carbon-fibre-reinforced plastic) bonnet, which lowers the car’s weight and centre of gravity further still. A wide front air intake optimises airflow and minimises front axle lift.

The dynamic and exclusive presence of the BMW Concept M4 GTS is accentuated by the exterior paint shade Frozen Dark Grey Metallic, with the Acid Orange accent on the front splitter creating an effective contrast. The lightweight, forged and polished light-alloy wheels in 666 M styling also feature an Acid Orange accent. The 9.5 J x 19 (front) and 10.5 J x 20 (rear) wheels are fitted with Michelin Sport Cup 2 tyres (265/35 R19 at the front, 285/30 R20 at the rear). The mixed-size tyres provide the ideal conduit for the stand-out dynamic attributes of the BMW Concept M4 GTS.

Water injection: power up, full-load fuel consumption down.
The engine powering the BMW Concept M4 GTS is equipped with the same innovative water injection system that has endowed the BMW M4 MotoGP Safety Car with a noticeable increase in output and torque.

The water injection system introduced by BMW M Division sees the engineers using the physical effect of water when vaporising to draw the required energy from the ambient medium. The water is injected into the plenums of the intake manifold as a fine spray. When the water vaporises, the intake air cools significantly. As a result, the final compression temperature in the combustion chamber – and therefore the engine’s tendency to “knock” – is reduced, enabling the turbocharged engine to use higher boost pressure and earlier injection timing.

This technology ensures an increase in output and torque, while at the same time reducing the thermal stress on performance-relevant components. All of which also enhances the stability and durability of the turbocharged engine. The BMW Concept M4 GTS therefore brings high-performance technology directly from the race track to the road.

The strong performance potential of the turbocharged six-cylinder in-line engine already demands an exceptionally sophisticated thermal management system for the engine and ancillary units. To ensure optimal operating temperatures in all situations, the M Division engineers have developed a highly innovative and effective cooling system. It comprises a main radiator plus additional radiators for the high- and low-temperature circuits, transmission and turbocharger in order to keep temperatures stable. The turbochargers are cooled by means of an indirect intercooler, assisted by an additional electric water pump.

OLED rear lights radiate ultra-high precision.
The BMW Concept M4 GTS is fitted with innovative rear lights featuring OLED technology. OLEDs (organic light-emitting diodes) are a new type of light source producing full-surface and homogenous illumination – in contrast to LEDs, which emit light to a single point. Their low installation height of just 1.4 millimetres and the ability to actuate individual light modules separately create fresh design scope in lighting concepts. OLED technology enables extra flexibility and forges an unmistakable appearance that signals exceptional precision.

OLED technology heralds a new era in light design and lighting concepts, and opens up new possibilities when it comes to a characteristic and distinctive light signature for BMW models – both for their daytime driving lights and during the hours of darkness.
